Librato was built as a generic monitoring service so there are many
ways to collect metrics.

The fastest and easiest way to get started is to use one of the
Librato Integrations. These solutions offer the
quickest path to get from configuration to curated dashboards
for things like servers metrics, Docker, Redis, AWS Cloudwatch and
many other services.

For more generic metrics you can choose from a large number of collection
agents and language bindings. These libraries allow you to
instrument your code or use local aggregation agents such as statsd to
collect any metric you desire.
